Geometry Considerations - Radii:One of the single biggest cost drivers for machined parts is
the length of time it takes to machine it. The rigidity and
strength of the actual cutting tools often determines how
much time it takes. Very simply, the shorter a tool is, the
faster it can feed, and the less the part will cost to make. The
selection of these cutting tools is determined by the design of
the part and a few simple rules can really help reduce
machining time.
When designing parts that have pockets, or other features
with vertical inside corners, you will need to leave a radius as
the machining process uses rotating tools. Use the largest
